Residents and businesses in southern Montgomery and northern Warren Counties in southwestern Ohio long discussed the possibility of increased capacity, including an additional interchange on Interstate 75 (I-75) between State Route (SR) 725 and SR-73, and/or an interstate-level southwestern beltway connecting I-75 south of Dayton and I-70 west of Dayton.

The Montgomery County Engineer’s Office administered a Major Investment Study (MIS). The purposes of this MIS were:

to identify and evaluate transportation issues based on existing and future conditions in southern Montgomery and northern Warren Counties in the vicinity of I-75 and in the southern portion of the area proposed for SR-892, and

to evaluate the potential for alternative transportation solutions to alleviate identified problems.

The study was designed to include alternatives for evaluation including, but not limited to:

an additional interchange on I-75 with a new connector roadway to SR-4;

an additional interchange on I-75 without a new connector roadway to SR-4;

improvement of local roadways without an additional interchange; and

a no-build alternative.

The Miami Valley Regional Planning Commission (MVRPC) participated on the study steering committee, as did the Dayton Area Chamber of Commerce, the Montgomery County Department of Economic Development, ODOT, the Federal Highway Administration, the Montgomery County Transportation Improvement District, and the Warren County Engineer’s Office. The study was on MVRPC’s 2025 Long Range Plan.

Austin Pike Area MIS Recommendations

The Montgomery County Engineer’s Office administered a Major Investment Study (MIS). The following recommendations were developed to address the study goals and the transportation issues identified within the study area. These recommendations were endorsed by the Transportation Committee on April 3 2003.

Improve east-west access to and from I-75 and improve operation of SR-725 and SR-741 by constructing an additional local interchange on I-75 in the vicinity of Miamisburg-Springboro Pike/Austin Pike.
